CYW920819EVB-02 and HC-05

[JiKa]

Hello,

I am trying to connect microcontroller  CYW89820 in SPP mode to HC-05 in master role.

I can see in HC-05 the address and device name of CYW89820. But when HC-05 is trying to connect (by bind command AT+BIND=2081,9A,156668), i just get the message from cypress "Pairing Complete: 5app_management_callback 3remote address = 98 d3 b1 fd 8a 86 app_management_callback 11Pairing Complete: 5". I am using the RFCOMM_Serial_Port demo program.

the Error 5 is comming from p_pairing_info-> br_edr.status, can you explain what is this number.

thanks

I don't know what's the HC-05 is. Please check the error code explanation in the bluetooth spec.

Hello, the HC-05 is the bluetooth module like for arduino (https://www.sgbotic.com/index.php?dispatch=products.view&product_id=1939). We would like use it for testing of communication with CYW920819EVB-02. 

What is default pin or link Key?

Do you have please link to bluetooth spec?

Thank You.

The application demo only support just works pairing procedure. Please check the peer device about it.

You may also test the connection with a spp app on your phone.

Hello, 

thank you for reply, it seems that HC-05 is Bluetooth version 2.1. It doenst support to pair without passkey and it is not compatible with our CYW89820 bt ver 5.0.

Would you have a link to Bluetooth spec mentioned above?

Thank you.

If you are looking for the bluetooth spec, you can download the latest version here: https://www.bluetooth.com/specifications/specs/core-specification/

You can refer to Vol 3, Part H, 2.3 for the pairing methods.
